Google's blog post regarding the answer to the code glitch starts with "If you did a Google search between 6:30 a.m. PST and 7:25 a.m. PST".This post was written by the Google team to mark the end to the error which was appearing when you clicked on the search result of Google between 6:30 a.m. PST and 7:25 a.m. PST.But what I dont understand is that the company like Google has direct to live codes.My point here would be very well understood by any tech chat Guy.The point is does not Google follow a SDLC (Software Development Life Cycle).How can a code change directly go to live website code without getting inspected.If it was a small website we would have understood but a billion dollar company like Google does this...I seriously dont understand.

How can a code change in Google Website go directly to live Website?
